my question is1) how to deal with the society,can i put a case on my society thru a lawyer or there is some other means as i am loosing on rental
You can issue a legal notice to the secretary if he is objecting and refusing to allow a tenant to occupy the flat. He has nothing to do with the flat being let out on rent by the authorised member of the society, the bye law is very clear about associate member's rights. However since your wife is a co-owner she may approach court of law with an injunction suit seeking to restrain you from letting out the entire premises on rent without her consent.
That will be a embarrassing situation to you.
2)can i proceed with filing the declaratory suit to remove her name from the flat or I have ton wait till the divorce case is over
This is not maintainable in law becasue she is a joint owner, hence her name cannot be removed based on your matrimonial disputes with her or for any reason.
3)can i get custody of my children as she doesnot care about the children .she doesnt want to leave her job and care for the kids.she has kept one son in Goa And Daughter is with us.after divorce too she wants to keep both the kids in Goa with mother so seeking joint custody wont help.they donot allow me to speak to my son for past 6 years.isnt this mental harassment or only men face harassment charges in court
What were you doing for all these six years when you were not allowed to even speak to your child.
As a biological father you have an equal right on your children similar to her.
You could have approached court of law with a child custody case and also visitation rights as interim relief.
Even now you can file a child custody case and argue the issue based on the merits to convince the court your plight and your love and affection towards the children.
